introduction: timely diagnosis and treatment of post traumatic, elevated intracranial pressure (eicp), could reduce morbidity and mortality, as well as improve patients’ outcome. this study is trying to evaluate the diagnostic accuracy of sonographic optic nerve sheath diameter (onsd) in detection of eicp. methods: sonographic onsd of patients with head trauma or cerebrovascular accident suspic...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

background and aim: low back pain is a common complaint in communities which has negative effects on different aspects of life. an effective method for reduction of low back pain complications is foot reflexology. foot reflexology has a positive effect in reduction of complications in low back pain. foot reflexology reduces respiratory rate, blood pressure and pulse rate. this study is an inves...

Pore pressureis defined as the pressure of the fluid inside the pore space of the formation, which is also known as the formation pressure. When the pore pressure is higher than hydrostatic pressure, it is referred to as overpressure. Knowledge of this pressure is essential for cost-effective drilling, safe well planning, and efficient reservoir modeling. The main objective of this study is to ...

abstract  introduction: hypertension is a very common cardiovascular disease with extensive effects on body organs. this study was conducted to compare the extent of target organ damage in hypertensive patients with and without significant nocturnal fall in blood pressure (dippers and non-dippers, respectively). methods: one-hundred patients with recently diagnosed hypertension underwent 24-hou...

the main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the qeshm channel. for this purpose, the curves of the pressure on the persian gulf and oman sea, during the passing of the atmospheric low pressure system, are extracted across the region. during the time of occurrence of these events, sea level oscillations in the coastal areas of...
